Certainly not much about Objective-J yet here on SO. Maybe it'll pick up when Atlas comes out. The webcasts are stunning. Is the language itself (Objective-J) changing much at this point? Or are you mainly addressing bugs and adding Cocoa-like functionality.

Thank you - helpful link. The documentation is still a bit sparse though. I was wondering whether there may a book coming out at some point. Maybe an O'Reilly book?

The language itself is pretty much stable and has been for a good year or so (aside possibly fixing bugs people may find).

I recently took up learning cappuccino. I found the Cappuccino Casts and the tutorials on cappuccino.org, however, like you, I come from a web development background - not cocoa / desktop apps.

Following some online tutorials was good to a degree, but I felt I lacked fundamental knowledge about the Objective-C and Cocoa and Cappuccino is modelled so closely to it. I bough a copy of Aaron Hillegass' book called "Cocoa(R) Programming for Mac(R) OS X" here: http://www.amazon.com/Cocoa-Programming-Mac-OS-3rd/dp/0321503619/ref=pd_sim_b_3 which I felt really helped with my base understand of application development rather than traditional web development.

I would definitely recommend giving it a read, I worked my way through it in a few days and thought it gave enough knowledge to understand what all the Cappuccino stuf was about.
